Which of the following selection pressures is responsible for the limited evolutionary changes experienced by alligators and other crocodilians?

Answer
A
stabilizing selection
B
directional selection
C
disruptive selection
D
high mutation rate

Explanation

Stabilizing selection favors individuals with traits close to the current average and selects against major differences. This can keep a successful body form relatively unchanged over many generations, explaining the limited evolutionary changes in alligators and other crocodilians. Therefore, the correct choice is stabilizing selection.
